Do you have old calendars around? Old calendars can be used
again in a year that starts on the same day. Of course lunar markings and holidays based on the
lunar calendar won't be in sync. But the days of the week will line up.
The java-script program below lets you type the year for which you want a calandar. When you press
"ok&quot, the results show what kind of year it is and what calendars from earlier years will
be good that year.
